1. A method for measuring channel quality in a wireless transmit/receive unit (WTRU), the WTRU being equipped with a smart antenna for generating a plurality of beams, selected from the group consisting of directional beams and an omni-directional beam, the method comprising the steps of:

  • (a) providing a dwell time in a measurement period to switch a beam from an active beam to a non-active beam, the active beam being a beam for communication with a serving base station;

    (b) switching a beam to a non-active beam at the initiation of the dwell time;

    (c) receiving signals from the serving base station and a non-serving base station through the switched non-active beam at the same time;

    (d) generating samples of the received signals;

    (e) storing the samples in a memory;

    (f) measuring a channel quality to the serving base station and a channel quality to the non-serving base station, respectively, using the stored samples; and

    (g) switching the beam back to the active beam.
